To al?, whom it concern:

Be it known that I, HENRY F. POPE, of

Cleveland, inthe county of Cuyahogaand' State fof Ohio, have invented anew and useful Improvement in Radial-Draft Gears, of which the followingis a full, clear, and eX- act description, reference being had to theaccompanying drawings, forming part of this specification, in `which-lFigure 1 is a plan view partly in section; Fig. 2 is a verticallongitudinal section of the parts shown in Fig. l; Fig. 3 is a cross ysection on the line III-III of Fig. 2; Fig.

` construction of the frame of the 4 is a sectional plan view showingthe device as used with Master Car Buildersl coupler; and Fig. v5 is asectional elevation of the same. f'

One purpose of my invention is to pro# vide a 'radial draft gear adaptedto receive and hold car couplers having shanks of varions-sizes. Q Asradial draft gears arenow constructed, they are provided -with couplersof special'design having a broad shank adapted to fit within the frameof the draft gear and to back and brace the lateral stopflange of' thecoupler head lin such manner as to prevent their breaking, a'nd one ofthe purposes of my invention is to'provide a draft rig* ging of suchcharacter that it will receive not only the couplers of thisconstruction, but ordinary couplers of the: Master Car Builders typehaving smaller Shanks.

Another purpose of my invention is to preferably construct the gear insuch manner that the center line of the coupler shank will be heldthereby in line with the center line of the draft rigging, and alsopreferablyinline with the center line of the pivotal support of thedraft rigging and with the central plane of the sills, so that lthedraft gear will swing horizontally in the plane of the center line ofthe sills.

In the drawings, 2 represents the head of a coupler which is of specialconstruction, having a broad shank 3, and lateral stops 4, 4, whichproject horizontally from the sides of the coupler so as 'to match withcorresponding stops of an opposing coupler and to hold the couplers frombuckling underlouling stresses. rlhe shank of this coupler is mountedwithin a frame, shown 1n section in Fig. 3, having top and bottommembers 5, 6, and side members 7, 7, which are preferably anged andiitted together,l i as shown,

and are held by suitable securing cial coupler shown in Fig.

4'and bottom recesses 9, 9,

vbolts 8. The portion ofthis frame which incloses the coupler shank isshown in section in Figs. 1 and 3, and the portion there- 'ofwhichinclosesthe draft rigging back of the couplershank is shown inpartial section in Fig. 1. -The portion of the frame which incloses thecoupler shank is made interiorly of the cross sectional dimensions ofthe said shank and has on the top and bottom members 5, 6, internalrecesses 9, 9, of the width of the corresponding portion of the shank ofan Aordinary Master Car Builders coupler, so that if the couplershownvin the drawings is removed from the frame, it can be replaced bysuch Master Car Builders coupler, which in that case will tit be-A tweenthe top and bottom members, and Will be held within the limiting wallsoffthe recesses 9, 9, as shown in Fig. 5.

10 is a filling block or buihng block, which' is seated within the frameat the rear end ofthe coupler shank and is backed by internal projectingflanges 11. This block is of-suitable strength to receive the bufiingstresses and to'transmit them through the flanges 11 to the frame. Whenthe coupler shown in Figs. 1 and 2 is placed in the frame, the rear endof the coupler shank abuts against the face of the block 10, and ispreferably of about the same cross sectional dimensions, so as to havecontact with the entire surface' of the block. The

coupler shank is then rigidly secured to the fside members of the frameby lateral bolts or keys 12, which extend through the sides .of theframe and through horizontal holes When the spe- 1 is removed fromthe'lframe and replaced with an ordiin the shank .of the coupler.

pler'fits within theA frame and within the. top and abuts at its rearend against the illing'block 10, and

nary lMaster Car Builders coupler, as shown `in y-Figs.' 4 and 5, theshank 3 of this coubeing of less cross sectional dimensions than thesurface of said block it does not bear upon the entire surface thereof.To receive such Master Car Builders-coupler, the top and bottom membersof the frame are provided with vertical holes spaced to match thevertical rivet holes in the usual liner block of a Master Car Builderscoupler, and when the coupler shank is putin position within the frame,it is held by vertical bolts 13 which pass through these holes in theframe and in th coupler shank.-

' on the yoke of a The bolts of both forms of the coupler are relievedof buing strains, for the reason that the coupler abuts against thebufiing block 10, and transmits its stresses thereto, and there are alsopreferably lips 14, formed' on the forward ends of the top and bottommembers of the frame which engage'the forward surfaces of thelinerblocks of the Mas-` ter Car Builders coupler, in order to relieve thebolts from stress during pulling, and thus to serve the functions of theusuallips coupler. As shown in Fig.

preferably provided" 15, which rests upon the coupler carryiron 16, andis secured to the frame of the draft gear by means of the forward bolts8, which tie the bottom mem- 2, the frame is also with a wearing shoe4desirable bers to the sidemembers.i Thiswearing-shoe has lugs 15 at itsforward endv which fit within holes on the under side of the couplershank, so as to hold the shoe to the shank during the lateral movementsVofthe coupler.- The purpose of the shoe is to relieve the shank fromwear during lsuch lateral movement. Car Builders coupler is inserted 4inthe l frame, it will also rest upon and will hold scribed.

the draft gear, -and an ordinary end of ing pulling,

the wearing-shoe in the same manner, except that the lugs 15 fit at thesides of theV coupler shank,` as shown in Fig. 4, instead of ttingwithin vertical holes in the shank, as in the case of the specialcoupler above de- It will thus be seen that in case of' injury to thespecial coupler which is designed for it may be removed readily l MasterCar Builders type substituted therefor withoutv special preparation. Insuch case, the shank of the Master Car Builders coupler Willt againstthe filling -block 10,) and -will transmit the stresses of buliing tothe frame of the draft gear, and thence to the draft ri ging, thusrelieving from strain the bolts w ich fasten the coupler shank to theframe.

The preferable arrangement of the draft rigging is shown in Figs. 1 and2. The draft rigging is set within the frame and provided with suitablefollowers 17 `and 17 and the. yoke 18 of the draft rigging Ipasses infront of the front follower 17 and `extends back to the' vertical pivotpin 19, on`.which the draftgear is pivoted, so as to swing horizontally.The frame isl'slotted, as at 20, or otherwise so constructed that duringbuffing it will move over the pivot .19, and in so doing will fcrcethefront follower 17 against the spring rigging and will com ress the same,the rear follower' du'ring bu g-being held by and' abutting against theforward thebracket 21 on the car frame, which the pivot pin passes.@Durthe front follower 17 remains stationary, being held by the forwardend of the yoke through When an ordinary Master I yin `modified uses, ortol modified' constructions 18, and the rear follower ,17 is drawnforward by its engagement with stops 22 on the side members ofthe draftgear frame. The frame is guided from the truck by means of alguidingconnection, a

form of which, shown in the drawing, consists of an arm 23, which isslidingly cnnected at its forward end at 24 with the bottom memberv ofthe draft gear frame and extends rearwardly to a vertical pivot pin 25-on the truck bolster `26. This arm 23 is held yieldingly by a rod 27which passes through a slot inthe arm 23, and carries springs 28,interposed between the arm 23 and brackets 29, which project from thetruck bolster and carry the arm 23.-

Forthe purpose of supporting the vertical pivot pin on which the draftswings radially,gI preferably provide the rear carryiron 30, of thedraft gear, with a bracket 31 .which projects under the vertical pivotpin y 19, so that in case the pin should break, .the

bracket 31 will hold it from dropping, although other pin supportingmeans may be'V rovided.

y constructing the'car with the proper dimensions between the truckbolster 26 and the end sill of the car, the draft gear frame may beadapted to receive any kind of draft rigging which is now in use, andwhen the ordinary Master Car Builders coupler is inserted in the frameitl will not project beyond the end Sill more and standard distance.

As shown in the drawings, the center sills 32 ofthe 'car frame aresoplaced that the longitudinal center line of the coupler shank iscoincident with the longitudinal center line of the draft rigging and itis also coincident with the center line of the pivotal support 19 andwith he central plane of the center sills, so that the draft gear willswing horizontally in the" plane of the center line of the center sills.As the support forming the resistance has its center substantially inthe center line of the center sills, the bufting 'stresses will beimparted to the draft gear equally in its upper and lower portions,thereby parts ofthe draft gear upwardly or downwardly. This also resultsfrom the center lineof`the couplerbeing in the horizontal center `lineof the pivotal bearing.

In theV drawings, I show myy device in what I deem to be its preferableform, but

` it will be understood bythose skilled in the art, that it is capableof many modifications,

form vand construction to adapt it to than the ordinary l avoiding anytendency to deect of the coupler draft gear or spring rigging which Ihave specifically shown -and dearranged to receive the shank of acoupler, said socket being recessed to receive the narrower shank ofanother coupler. v
